My invention'relates yto sprays and hasfto do more particularly with devices .orprol dueinga spray of inelyatomizedliquid maf terial such as paint-or otherV pigment, disin` ectant', .fungicides and .'insecticides, etc. I.

An object of myinvention isV to kprovidea device forproducing a spray of material in a quantityfvariable at the will or" an operator and for any desired length of time with slight 1 0 Aeffort on thefpart of the operator.'A Y =Afurther object -isto produce a device of the class4 describedwhich willcconsistoi:l ka

small number ofzrelatively simple parts, (the devicev being inexpensiver tov manufacture,

v 1,6 rugged, and-easy kto operate.- v

Manyother..v objects and advantages otrthe K construction herein shown and described will be obvious=tothose skilled inthe art from the disclosure herein given. f :Le Togthis end my invention consists in the novel' construction, arrangement andKV combination of parts herein shown and described, and 1 more particularly ypointedV out in lthe claims. f

In kthe particulark preferred embodiment shown in the drawings, the numeral indicates a container of any desired'shape', size the cap-llllprovides communication be# 'i tween the linterior of thetubular membe'rl and the. interior of` the containerl 1 0. l

yA tubular valve casing 2Q is secured to insideof thelcap so as to project downwardly linto the container 10- this casingV communicat-- ing with the interior of theptubular member 15.* Seated within the; upper PQX'OD 0f the tubular member 2O and communicating theref *with7 is afcurvedtubular member v'23,; this 'tubular member terminating within the lapercture 18. It will'be noted-from F ig. l that the v end of the tubular member V23 is substantially flush andv concentric withthe aperture, an

Vannular spacev being `provided between the *tubular member 23 and thewalls of the aperture.

Slidably4 disposed within the valve f2() isaJtubular member 25,k an aperture or port 26 being provided lin the wallof this member. adjacent its upper` extremity and a notch 25l isfprovided infthe bottom thereof. A- valve member 28 formed on the end ofy the tubul'armember 2,5 is adapted to seat in the end of kthe tubular; member 23, ...this valve memberhavingahead portion 30. Thehead 30iis graduated in diameter, being substantially Afrusto-co-nical. yThe valve member is ,secured to the ,stem 25 by means oa ball jointl 28,,vthe ,valve head being/spun over yas at V31, so that this member is slightlyad-y justable within its seat.

As clearly shown in Figs. 1 and 2, the bore of thevtubular'member 20 is enlarged adjacent its upper end, as at 22, so as to provide a chamberl27 around the tubular member 25 and valve 28. f V j e Secured to the tubular member 25 by means of solder oro-ther suitable means isran arm y;carried by a rodv36. Therod 36 extends through` the tubular kmember 1.5 passing through an yaperture 37 formed in this member and in theca'p`13 and ya-n aperture 3,7.y in lthelmember 15, and is threaded at its upper Threadedly engaging the free end ofthe rod 36 is a'manipulating extremity as at 38.

member 39 having a knurled head 40,3511 helical spring 41 disposed on the rod 36` engages the lower portion of the manipulating member 39 and carries at itsl opposite endv an.

annular ring42 which bears against the tubular member 15, so that thev spring 41 is :compressed between this member and the manipulating member 39.

Inoperation, the tubular member 15 is connected toa suitable conduit 45 leading to any convenient,V source. of air pressure 1 (not shown). Suchrsounee of pressure may be a tially as indicated by "thelfull lines in Fig. 11. Y' i lVhenfth-'rsoccnrmwa portion ofthe air being n vacuum cleaner, an air pump, or.a. com@ pressed air reservo-1r.l inthe normal condif tion of the device, as indicated by-'tledotte'd lines in Fig. 1, the valve head will be seated within the openingof the tubular member 'EZB so as to `prevent the iowgof liquidthrough the tubular member 23, the valveY member'.

lbeing resiliently. v urged upwardly 1- Y by the desired to producea sp ray, the manipulating merliberv 39' is mannaliy depressed against the vaction 'of Vthe spring 4:1'.V 5 YThis resultsY in moving the rod 36 downwardly,fthis rod carrying with-'fit the tubular valve Lstem 25 se that' the bottomlof thisst'emfisadgacont the door of -the container 10, andfalso` moving downwardly the valveanember'QS, clf'aaringr the; entrance to lthe tubularmember v23. The posi-tion oft'he parts wilfthen be substan forced thronglrtheftubuiaraneinber 1'5 which passes'through the aperture 19 into the container 10 will force: the liquid up into the tubep25, fout ofthefpeit 26, into VAthe chamber 27, andV through Vthe tubularm'ember 23. Upon issuing Vtron-1 the end ofthe tubular ilnenibe'r 23, 'this liquid will encounter' afpon' tion `oiffth'e air which hasfbeen'sforced directly 'through fthe tubular member l15, this air vissuing romfthe aperture 118 in a strong eonicai 40V blast. The eiiect ofthis lair vcurrent around the o'peningothe l'tubularfn'iember 23 ils-to 'cause la violent dispersion-,of theliquid, 'thus producing a 'linely Avatomized cloud. V-The air issuing lromfthe .aperture '18Yalso tends to set up a vacuum within'the tube '-23 andthu's Yassists-iii raising the liquid from the container 10. v- When itis desired to cutoff the'spray, the `ina-1iipulating member is vreleased. The 'spr-ing; 41 thereupon immediately raises ythe rod V36 and the valve member land seats this member in the tubular member 23 so as to'y controlled by means of the manipulating member 39.A When it is desired to increase or decrease the volume of spray, theknurled head .l0 Vis rotatedin the proper direction. This resultsxin either increasing or decreasingk the distance between the knurled head 40 andthe top oi" the. tubular member 15 and 'thus varying the distance. that thisv memvvber may be depressed. Inasmuch as the valve displacement is equal to the displacement off'theknurled` head 40, it follows that the amountV of liquid passing through the valve will thus be varied.

lfhedeviceris V\ re ry easily carried to any point where the spray is desired, the conduit usually beinglexible. 'f' Thetubular member 15 may,if desired, be l.usedas ahande=-and the manipulating vmember displaced by.A the thumb,thns leaving theotherhandree;
